Abstract. The problem of flight delays is one of the key issues in the field of air transportation in Kazakhstan, having a significant impact on passenger service, airline operations and airport economics. Given the growth of passenger traffic and the active development of the aviation market, identifying and eliminating the causes of delays is becoming an important task to increase the competitiveness of the industry. The subject of the study is the causes of flight delays and their impact on the efficiency of airlines and airports in Kazakhstan. The study solved such tasks as analyzing the current state of flight punctuality in Kazakhstan, identifying the main factors influencing delays, assessing the economic and social consequences of flight schedule violations, and developing recommendations to reduce delays and improve punctuality. The purpose of the study was to study the causes of flight delays in the Kazakhstan air transportation market and to develop effective measures to minimize them.
The paper uses methods of statistical analysis, expert surveys, analysis of regulatory documents, as well as a comparative analysis of punctuality indicators of leading air carriers. The main results of the study were the identification of key causes of flight delays, including weather conditions, technical malfunctions, airport congestion and organizational factors, the analysis of flight delay statistics of the largest airlines in Kazakhstan, the development of proposals to optimize the processes of planning and management of air transportation.
As a result of the study, measures have been proposed to reduce flight delays, including improving the operational planning system, introducing digital technologies to predict delays, modernizing airport infrastructure, and improving the regulatory framework. The implementation of these recommendations will improve the punctuality of air transportation and improve the quality of passenger service in Kazakhstan.
